Application filed August 11, 1904- Serial N0. 220.399-

To all whom, it may concern:

Be it known that I, ABRAHAM M. ZIMMER- MAN, a resident of New Holland, in the county of Lancaster, and State of Pennsylvania, have inventedcertain new and useful Improvements in Pum -Buckets; and I do hereby declare the fol owing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved pump bucket or piston, the object of the invention being to provide an improved bucket with wood bushing to enable the outer leather packing and valve to be secured thereto by nails or tacks, which ermits the easy .re-

oi worn leather when desired; and t e invention consists in certain novel features of construction and combinations and arrangements of arts, as will be more fully hereinafter descri ed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation illustrating my improvements. Fig. 2 is a view in longitudinal section. Fig. 3 is a view in section on the line a; {13 of Fig. 2, and Fig. 4 is a view in section on the line y 'y of Fig. 2.

1 represents a metal casing or frame, having a lower cylindrical portion and upper yoked end 2, to be secured to the pump-rod. The lower end of the cylindrical ort10n of casing 1 is made with an inturned ange 3 to limit downward movement of my improved wood bushin 4, tightly fitting in the casing and made ho low, as shown, for the passage therethrough of the water. A leather valve 5 is secured to the bushing by nails or tacks 6 or e uivalent fastening devices and can be readi ly removed and replaced as may be necessary.

The cylindrical portion of easing 1 is made with an annular recess to receive leather packing 7, and the casing is made with a number of openings 8 in its recessed portion to permitnails or tacks 9 or other fastening device to be driven through the leather packing 7 and openings 8 into bushing 4, and these fastenin devices can be easily withdrawn when it 1s desired to replace the leather by a new acking.

While wood, I would have it understood that the have stated that bushing 4 is of bushing may be made of various other nonmetallic substance, and by constructing the bucket as above explained worn leather and valve can be replaced without difficulty and Without special tools, and there are no screws or nuts to rust or get tight. The leather lying on metallic surface always fits very close,

and if the new leather is cut over the same Having fully described m invention, what I claim as new, and desire to secure by Letters Patent, is A 1. A um -bucket comprising a metal cylindrica she I having a plain interior face, a tubular wooden bushing seated within said metal shell and having an unbroken peripheral wall contacting with the plain interior face of the metallic shell, a valve normally closing the end of the wooden bushing, a packing embracing the metal shell and fasten- 1n devices passing through said packing and slots in the shell and entering thewooden bushin 2. The combination with a cylindrical metal casing open at both ends, and provided at its lower end with an inwardly-projectin flange, and on its outer side with a eriphera shoulder, of a wooden bushing aving an open center and resting on said inwardlypro.

j ecting flange, a flap-valve resting on and secured directly to the up er end of said bushing, and normally 0 osing the opening through the bushing, and a packing resting on the peripheral shoulder of the casing and secured to the bushing by fastening devices passing through slots in the casing.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
